BRUSH.

To all whom it may concern Be it known that we, .Tosnrn. 'Enllqins TYIARC/IL, of the city of ivlrmlreal, in ihei county of I'lochelagafin the l rov ince o't (.Quel bec, a notary, and LOUIS Manon, ot the parish of St. ,lVllChG]-r kI'Cl12\llg(, in the trict otl' Iberville, in the Province oi: (Que bee, in the Dominion oil Canada, a farmer, have invented certain new and useful fl'mprovements in Brushes, and do hereby do clare that, the following is a full, clear, and exact description of the same.

The invention relates to improven'ients in brushes and the like, as described in the present specification and illustrated in the accompanying drawings that form part of the same,

The invention consists essentially in the novel construction whereby a central cavity is made in the face of a brush, said cavity having lateral grooves in its sides. ()ement or any adhesive substance is then poured in this cavity, where the bristles have already been disposed and expands into the lateral grooves, thus preventing the cement from breaking away from the body of the brush and producing an article of manufacture that will be exceedingly solid and durable.

In the drawings, Figure l is a longitudinal sectional side elevation tl'irough the brush, the bristles and cement having been removed. Fig. 2 is a cross section on the line A-B, in Fig. 1. Fig. 2-3 is a longitudinal sectional side elevation, showing the coment and bristles secured in the face ot the brush. Fig. at is a longitudinal sectional elevation of a modified :l orm ol. the brush.

Like numerals of reference indicate corresponding parts in each figure.

In the drawings, 1 is the body of the brush having the usual. face 2 and back 3.

4c is the handle.

5 is a cavity in the face 2 of the brush, said cavity being bordered by the sides 6.

7 are lateral grooves in the sides 6 ot the cavity 5, said grooves extending preferably through the entire thickness of the said sides 6 and being of any convenient size.

S is the cement or any suitable adhering substance which has been poured in the cavity 5 and expands into the lateral grooves 7 thus making it impossible for the cement to part from the body of the brush.

5) are the ordinary bristles used in the manul'm-ture o'l' brushes.

in Fig. i is shown a modified form in the construction of the brush. in which a longitudinal groove or slot 10 is made in the back 2; ol. the brush abutting into the bottom of the cavity 5. ll. is a veneer facing placed over the back ol? the brush. 12 is another veneer facing placed over the face 2 of the brush over the cement 8, said veneer facing 12 having the perforations 13 in which are inserted the bristles S). In this last form of brush, the cement is poured in through the slot 10, also expanding into the lateral grooves 7. while in the previous form described, the cement is poured in from the face 2. The bristles are then inserted in this cen'ient and left to dry. A veneer facing can be put on over this cement, if desired, in the more expensive brushes.

It will readily be understood that the shape of these cavities and grooves or passages have nothing to do with the invention and that any alteration in their shape might be made without departing from the spirit of the invention.

A ny convenient or known manner of bolding the bristles to the brush with their ends in the central cavity may be employed, the most common method being to first place each bunch of bristles in a suitably peritorated block or board with their one end uniformly projecting through one side of the perforations a short distance. A quantity of cement is now placed in said cavity, it being understood that the cement used for these purposes is oi. a pasty nature. The block be'tore mentioned. is now pressed against the inner face 2 of the brush so that the bristles enter the paste first. On Tillther pressure the cement is compressed within the cavity 5 and some of it finds its way into the lateral grooves or passages 7 thus completely filling said passa to form keys and at the same time presenting an even surface around the bristles on the inner face of the brush. The block is now removed, leaving the bristles firmly embedded in the cement.

In the :lorm described in Fig. 4, the process of inserting the bristles is very much the same with the exception that the paste is applied through the slot 10 in the back and an additional member is used to press the cement in from the back. However this process of inserting the bristles really forms no part of the present invention and no claim is made therefor.

lVhat We claim as our invention is:

1. A brush, comprising in combination, a body having a comparatively deep cavity formed therein, said body also having transverse passages extending through the sides of the body from said cavity to the outer sides of said body, a cement material filling said cavity and passages completely and bristles embedded in said filling cement.

2. A brush, comprising in combination, a body having a comparatively deep cavity formed therein, said body also having transverse passages extending through the sides of the body from said cavity to the outside thereof, a similar passage extending upwardly from said cavity to the top of said body, a cement filler filling said'cavity and passages, bristles embedded in said filler, and veneer coverings for the top and bottom of said body, said passages serving to lock the filler in position in the body.
